There is a box of cards in front of you with 9 heart cards, 4 spade cards, 7 club
cards, and 8 diamond cards. What is the probability of selecting a heart, not
replacing it, then selecting a spade, not replacing it, and on the third pick,
selecting a card that is not diamond? *

Step-by-step explanation:

16x^2 - 4

4(4x²-1)

4((2x)²-1²)

4(2x+1)(2x-1)

Answer should be,

4(2x + 1)2

Answer:

4.8 hours

Step-by-step explanation:

6=10$

divide by 10

0.6=1$

multiply by 8

4.8=8$

Answer:

4.8

Step-by-step explanation:

Well, if you work for 6 hours, and earn 10$, then, you are earning 10/6$ per hour. So, we can estanblish the equation:

10/6$ * x hours = 8$.

x = 4.8 hours.

Answer:

question 5) 43

question 6) 38

question 3) 107

question 4) 82

Step-by-step explanation:

question 5 and 6 add up to 90 so 90-47=43

and questions 3 and 4 add up to 180 so, 180-73=107

qnd 52+46 =98 so 180-98=82

Answer:

75720cm or 757.2m

Step-by-step explanation:

300m = 30000cm

78m & 60cm=7860cm

perimeter of rectangle = 2(length) + 2(width)

2(30000) + 2(7860) = 75720cm or 757.2m

Answer:

[tex]-1.5x - 3.5y =- 31.5[/tex]

Step-by-step explanation:

Given

AB: [tex]-7x + 3y = -21.5[/tex]

[tex]PQ(x_1,y_1) = (7,6)[/tex]

Required

Determine the equation of PQ

First, we calculate the slope of AB:

[tex]-7x + 3y = -21.5[/tex]

Make 3y the subject

[tex]3y = 7x - 21.5[/tex]

Make y the subject

[tex]y = \frac{7}{3}x - \frac{21.5}{3}[/tex]

An equation has the general form:

[tex]y = mx + b[/tex]

Where m = slope

So:

[tex]m = \frac{7}{3}[/tex] -- Slope of AB

From the attached diagram, we can see that PQ is perpendicular to AB.

This means that, the relationship between their slope is:

[tex]m_2 = -\frac{1}{m_1}[/tex]

Substitute 7/3 for m1

[tex]m_2 = -\frac{1}{7/3}[/tex]

[tex]m_2 = -\frac{3}{7}[/tex]

The equation of PQ is then calculated as:

[tex]y - y_1 = m(x - x_1)[/tex]

Where

[tex]m = m_2 = -\frac{3}{7}[/tex]

and

[tex]PQ(x_1,y_1) = (7,6)[/tex]

So, we have:

[tex]y - 6 = -\frac{3}{7}(x - 7)[/tex]

Multiply both sides by 7

[tex]7(y - 6) = -\frac{3}{7}(x - 7)*7[/tex]

[tex]7y - 42 = -3(x-7)[/tex]

Open bracket

[tex]7y - 42 = -3x + 21[/tex]

Collect Like Terms

[tex]3x + 7y = 42 + 21[/tex]

[tex]3x + 7y = 63[/tex]

Divide through by -1/2

[tex]-\frac{1}{2}(3x + 7y) = -\frac{1}{2}*63[/tex]

[tex]-1.5x - 3.5y =- 31.5[/tex]

The equation of PQ is: [tex]-1.5x - 3.5y =- 31.5[/tex]

Answer:

B. -1.5x − 3.5y = -31.5

Answer:

Step-by-step explanation:

3(-2)-15+2 = -6-15+2 = -21+2 = -19

Answer: -19

Step-by-step explanation:

3(-2)-15+2

Multiply the 3 and -2 because of the parenthesis first:-6-15+2

Next just put the negative numbers together:-21+2

Then just do -21+2=-19

Answer:

(2x+2y+7)(x+y+7)

Step-by-step explanation:

I suspect this is what you are expected to do.

Define z=x+y

2z^2+9z+7

2z^2+2z+7z+7

2z(z+1)+7(z+1)

(2z+7)(z+1)

(2x+2y+7)(x+y+7)

The cost of the t-shirt would be $19.20 with a 20% discount and the amount discounted is $4.80

Step-by-step explanation:

24*0.8 = $19.20

Answer:

Step-by-step explanation:

The discount is:

price × discount

We can substitute the discount of 20% for 0.2 and multiply to find the amount of money taken away which gives us the remaining amount or the amount you pay.

$19.20

Step-by-step explanation:

the quotient of 10 is bigger than the quotient of 50

The quotient is greater when number is divided by 10.

The division is the process of repetitive subtraction. It is the inverse of the multiplication operation. It is defined as the act of forming equal groups.

Given,

Krisa divides a number by 10

Let the number be x

x/10 = y  

x = 10y                ------(1)

Same number is divided by 50

x/50 = z

x = 50z               --------(2)

By equation (1) and (2)

10y = 50z

y = (50/10)z

y = 5z

⇒ y > z

Hence, quotient when number divided by 10 is greater.

Choice 2

Step-by-step explanation:

The downward sloping line has a y intercept of +1 and a slope of -2, hence its equation is y=-2x+1.  Since the shaded region includes some points on the line and above the line, we know that the relation must be >=.  Thus, one of the inequalities must be

y>=-2x+1

The upward sloping line has a y intercept of -2 and a slope of +1, hence its equation is y=x-2.  Since the shaded region includes some points on the line and below the line, we know that the relation must be <=.  Thus, the other inequality must be

y<=x-2

SAS for similarity

Step-by-step explanation:

I can tell you from this is that ∠TUS ≅ ∠WUV, because they are vertical angles.

The triangles cant be congruent by SSS, SAS, or ASA because the sides are not equal.

However, they are similar because 45/15 = 3 and 36/12 = 3. That would be the SAS for similarity.
